Answer:
(0 ; -1 ) , (1/4 ; 0) , (-1 ; -5)
Step-by-step explanation:
y=4x-1
x=0 y=-1
x=1/4 y=0
x=- 1 y= -5
so : three integer or decimal (0 ; -1 ) , (1/4 ; 0) , (-1 ; -5) you can draw the graph

Answer:
sin(θ)tan(θ)
Step-by-step explanation:
![\dfrac{\cos\theta}{\csc^2\theta-1}=\dfrac{\cos\theta}{\cot^2\theta}=\cos\theta\cdot\tan^2\theta=\cos\theta\cdot\dfrac{\sin\theta}{\cos\theta}\cdot\tan\theta\\\\=\boxed{\sin\theta\cdot\tan\theta}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ccos%5Ctheta%7D%7B%5Ccsc%5E2%5Ctheta-1%7D%3D%5Cdfrac%7B%5Ccos%5Ctheta%7D%7B%5Ccot%5E2%5Ctheta%7D%3D%5Ccos%5Ctheta%5Ccdot%5Ctan%5E2%5Ctheta%3D%5Ccos%5Ctheta%5Ccdot%5Cdfrac%7B%5Csin%5Ctheta%7D%7B%5Ccos%5Ctheta%7D%5Ccdot%5Ctan%5Ctheta%5C%5C%5C%5C%3D%5Cboxed%7B%5Csin%5Ctheta%5Ccdot%5Ctan%5Ctheta%7D)
Answer:
290 gramas
Step-by-step explanation:
Podemos interpretar a questão acima matematicamente como:
3 pacotes = 870 gramas
1 pacote = x
Multiplicação cruzada
3x = 1 × 870 gramas
Divida os dois lados por 3
3x / 3 = 1 × 870 gramas / 3
x = 290 gramas
Portanto, cada pacote conteria 290 gramas de carne moída
Answer:
The rotation of the rectangle, of area 12 squared units, about y-axis produces a cylinder, with a volume of 48
cubic units.
Step-by-step explanation:
Rotation about x-axis or y-axis at an angle requires some general rules. When a 2D figure is rotated about a line a 3d figure would be produced. This can be done through a process called solid of revolution.
From the question, connecting the given coordinates produces a rectangle with a length of 4 units and width 3units.
Area of the rectangle = Length × width
= 4 × 3
= 12 square units
The required rule for rotation of a figure about y-axis is: (x, y) → (-y, x).
If the given rectangle is rotated about y-axis, a cylinder would be formed.
The volume of the cylinder = V = ![\pi](https://tex.z-dn.net/?f=%5Cpi)
h
where: r = 4 units and h = 3 units.
V =
×
× 3
= 48
cubic units
Therefore, the rotation of the rectangle of area 12 squared units produces a cylinder with volume of 48
cubic units.
